Human aging is a biological process, no one can stop, but delay it. It is possible that one person has a physiological younger than his or her biological if one engages in healthy living life style and eating healthily by increasing the intake of good healthy food such as whole grain, fruits, vegetables, beans and legumes, etc. and reducing the consumption of harmful foods, such as saturated fat, trans fat, artificial ingredients, etc.

                            Theories of aging 

What cause aging? The question that has been asked throughout the human history, but it doesn't seem to get any answer but raises many more unanswered question. While many theories try to answer the question by related aging to tear and wear of the body, others deal with how the organs and systems in the body develop and deteriorate overtime, etc.

                  The Theory of  Hayflick limit

The Hayflick limit (or Hayflick Phenomena) theory discovered by Leonard Hayflick and a biologist in 1966. In vitro study, the number of times a fibroblast diploid cells will divide before it stops. The discover is conferring a major hypothesis if the cell division can prolong in a infinite matter without conditions which cause damage of the cells, then organism can liver forever.
Exceptions:
Stem cells
Since stem cells can continue to regenerate new cells for the entire lifespan of the organism, without limit, thus constituting a notable exception to the Hayflick limit theory.
Cancer cells
Cancer cell in biological aspect, have found a way around the limit by becoming a group of immortalized cells produced from cell division that have no limit as to how many times this immortalized cell division might take place.
